Synopsis for “Giant-Man versus the Wonderful Wasp!”
Working in his lab, Henry Pym has found a way to speed up the growth of plants, however his experiment soon gets out of control and the plant grows rapidly causing it to spread about the city. Shrinking down to ant-size, as Giant-Man he manages to stop the plants further growth by destroying it’s tap root. However the plant still continues to grow (unknown to Pym), and when two-bit crook Second-Story Sammy makes an escape from a botched robbery, he ends up landing on one of the plants leaves and sliding into Pym’s lab. There Sammy spies Pym’s continued work on his experiment which causes an explosion that knocks him out.
Checking the unconscious body, Sammy learns Giant-Man’s secret identity and decides to steal his costume, properly deducing that it’s the source of Giant-Man’s size changing powers. Learning a rudimentary understanding of how the costume works, Sammy storms out of Pym’s lab to start a crime spree, but not before bumping into Janet Van Dyne on his way out, who follows after him as the Wasp.
Somewhere in the city, Sammy finds a jewelry store and robs it, but not before setting off the alarm and alerting the police. Learning of the robbery, the Wasp tracks Sammy (who she thinks is Henry Pym) and attacks him inside the jewelry store. At ant-size, the Wasp easily defeats the inexperienced Sammy, demanding to know where the real Giant-Man is.
Meanwhile, the plant continues to grow out of control, Pym wakes up and learns what’s been going on since he was knocked out. He soon sees that the Wasp has been trapped in a glass jewelry box and sends on his ants to capture the faux Giant-Man. Carried back to Pym’s lab, Pym easily dispatches Sammy with one punch, then with the aid of his ants finds and destroys the real tap root to the giant plant stopping it’s further growth.
The Wasp frees herself and returns home to find the real Giant-Man waiting for her, the two heroes then turn over Second-Story Sammy to the police and clear Giant-Man’s name.
